TM Forum’s Multi-Technology Operations Systems Interface (MTOSI) is an NGOSS-based interface for managing network resources and connectivity and the associated services in the following areas of the Business Process Framework (eTOM):

• Resource Management & Operations (RM&O)
• Resource Trouble Management (RTM)
• Managed Resource Inventory (MRI)
• Resource Provisioning (RP)
• Resource Performance Management (RPM)
• Service Management & Operations (SM&O)
• Service Configuration & Activation (SA)
• Service Activation Interface (SAI)
• Service Component Activation Interface (SCAI)

The MTOSI Interface model, which is shared with the Multi-Technology Network Management (MTNM) interface, consists of a generic view that is derived and developed at different abstraction levels with different interaction patterns in order to cover both fine grained interactions and the coarse grained services.

Such innovative modeling concepts allow the single interface, using one model and consistent operations paradigm, to manage many disparate network technologies (SDH/SONET, WDM, ATM, DSL, Ethernet, Wireless, etc.) even where these technologies are intertwined within a single network device.

Release 2.0 of the MTOSI product is a major release with a number of new features including:

• Service activation management
• Resource provisioning and activation
• Management of connectionless networks
• Performance management and maintenance commands
• Inventory updates, multi-event inventory notifications and enhanced inventory retrieval (attribute value matching)
• Enhanced model for resource states
• Multi-action and request transactions
• Division of deliverables into Document Delivery Packages (DDPs)
